A Python-3 (CPython >= 3.5.0) Interpreter written in Rust 🐍 😱 🤘.

To test RustPython, do the following:

$ git clone https://github.com/RustPython/RustPython
$ cd RustPython
$ cargo run demo.py
Hello, RustPython!

Or use the interactive shell:

$ cargo run
Welcome to rustpython

RustPython is in a development phase and should not be used in production or a fault intolerant setting.

Our current build supports only a subset of Python syntax.

Contribution is also more than welcome! See our contribution section for more information on this.

Checkout those talks on conferences:

• FOSDEM 2019
• EuroPython 2018

Allthough rustpython is a very young project, it is already used in the wild:

• pyckitup: a game engine written in rust.
• codingworkshops.org: a site where you can learn how to code.

• Full Python-3 environment entirely in Rust (not CPython bindings)
• A clean implementation without compatibility hacks

Currently along with other areas of the project, documentation is still in an early phase.

You can read the online documentation for the latest release.

You can also generate documentation locally by running:

$ cargo doc # Including documentation for all dependencies
$ cargo doc --no-deps --all # Excluding all dependencies

Documentation HTML files can then be found in the target/doc directory.

Contributions are more than welcome, and in many cases we are happy to guide contributors through PRs or on gitter. Please refer to the development guide as well for tips on developments.

With that in mind, please note this project is maintained by volunteers, some of the best ways to get started are below:

Most tasks are listed in the issue tracker. Check issues labeled with good first issue if you wish to start coding.

Another approach is to checkout the source code: builtin functions and object methods are often the simplest and easiest way to contribute.

You can also simply run ./whats_left.sh to assist in finding any unimplemented method.

As of now the standard library is under construction. You can use a standard library by setting the RUSTPYTHONPATH environment variable.

To do this, follow this method:

$ export RUSTPYTHONPATH=~/GIT/RustPython/Lib
$ cargo run -- -c 'import xdrlib'

You can play around with other standard libraries for python. For example, the ouroboros library.
